I'm sure you're correct, Bob, but my understanding is that stalls in
the circuit are a well-recognised cause of accidents? If so, it might
not be as automatic as you suggest for a novice.


With 1500 RPM and the nose below the horizon, the airplane
WILL NOT stall. :-) There are some qualifications to this
generalized statement, learn what the runway looks like on a
stabilized approach and just always put the nose in that same
position every time, it WILL NOT stall.

I think the danger time is that turn onto final - too late, therefore
too steep, student gets fixaxted on the approach and the airspeed decays
in the turn.

I mean... how many planes have stalled in that turn in history???

The turn from base to final is a bad place to stall. When someone stalls
inadvertently on that turn it is rarely, if ever, because they got too steep
in the bank. Pilots these days have been so thoroughly brainwashed that
they will NOT bank greater than thirty degrees in the traffic pattern.

When they find they are overshooting the turn and will be wide of the runway
they carefully hold their thirty degree maximum bank like they were taught
and then rush the turn by pouncing on the inside rudder to get the nose
around quicker. This doesn't really stall the whole airplane. It only
stalls the inside wing. The outside wing, which is still flying fine, then
proceeds to fly up and over the fuselage until it is the inside wing.
Unfortunately the resulting inverted position generally results in a quick
split ess maneuver that soon terminates when the airplane lands from the
inverted dive that results. This is not actually a spin because the
airplane generally contacts the ground at high speed before the spin has
time to properly develop.

Even a fortyfive degree bank only increases the stall speed by about
fourteen percent. The normal approach speed is about thirty percent above
stall speed. Consequently even a fortyfive degree bank in the pattern still
leaves you a fifteen percent margin. In a Cessna that is about five knots.

Of course, I must admit, I see few private pilots these days who can hold
their airspeed within five knots in a fortyfive degree bank. :-)

Personally, I have lost three good friends due to stalls on base to
final. Two in an RV-6 in 1989 and one in a T-6 in 1999.
